Encoding of LTM- Baddeley (1966)

Aim - Investigate the nature of LTM coding.

Procedure - Baddeley constructed a pool of short, familiar words for each of four catagories, and agreed with Conrad. Baddeley modified his experiment to test LTM. He extended the length from 5 words to prevent rehearsal by interrupting them after each presentation. Each list was presented four times and then recalled after a 20 minute interval.

Results - Under these conditions, he found that acoustic similarity had no affect on recall but that words with similar meaning were poorly recalled

Conclusion - LTM codes mainly semantically

Evaluation - Lab experiment so it is therefore artificial
- No serious ethical issues
- Consent is needed.
